ABSTRACT

A portable seat apparatus including a support seat having a support seat body sized to support a user&#39;s back, the support seat body having a first end and a second end opposite the first end, the second end sized to terminate a distance above a user&#39;s hamstrings, at least one strap coupled to the support seat body and configured to surround a user&#39;s body part, and a support assembly including a base couplable to a ground surface and a height adjustable support column having a proximal end opposite a distal end, the proximal end coupled to the support seat and the distal end rotatably coupled to the base such that the proximal end of the support column is rotatable toward and away from the base.

FIELD OF THE INVENTION

The present invention relates generally to seating apparatuses, and, more particularly, relates to a portable seat apparatus configured to provide back support.

BACKGROUND OF THE INVENTION

Specially designed seats have been known and utilized for some time which support a user's back in an effort to alleviate back pain. For example, kneeling chairs have been utilized in which a user is required to kneel onto the kneeling chair to maintain the user's spine in an upright and neutral position. Such kneeling chairs require the user to kneel down with the user's knees pressed against a padding. Unfortunately, kneeling down on the padding may be difficult and uncomfortable for users when the kneeling chair does not allow for height adjustment. As an added disadvantage, such kneeling chairs often fail to include a back support surface that the user may lean against for back support. Moreover, once positioned on the padding, the user is confined to the location of the chair because the chair is not designed to move with the user. As such, the user is limited to performing stationary tasks, such as desk work, while using such kneeling chairs.

Many known height adjustable seating apparatus, e.g., “stools,” are configured to allow user mobility without subjecting a user's back to pressure. Such stools often include a seat designed to support the user's buttocks only and do not include a back support piece. Unfortunately, failure to include a back support piece often increases back pain because the user cannot utilize the back support piece for stabilization. In addition, such stools limit the user's ability to move with the stool. More specifically, when the user desires to move the stool, the user must manually hold the stool or remain seated and rely on one or more wheels to move the stool and user across a ground surface.

At least one known seat provides a user with the ability to lean against the seat while placing the user's feet on the ground with the user's buttocks positioned on the seat to center and stabilize the user's weight. Such seat includes a height adjustable pole, a foot, and a seat cushion. Unfortunately, the seat fails to include straps to couple the user to the seat, thereby making it relatively easy for a user to slide out of or otherwise lose balance when attempting to sit in the seat. As an added problem, the leaning seat fails to include a back support piece to provide back support to the user.

Therefore, a need exists to overcome the problems with the prior art as discussed above.

DETAILED DESCRIPTION

While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.

The present invention provides a novel and efficient portable seat apparatus having a support seat configured to sustain the weight of the user sitting on and leaning against the support seat for back and buttock support when the user is bending down or in a squat position. Embodiments of the invention include the portable seat apparatus including at least one strap configured to couple the support seat against the user's back in a harness like configuration. In addition, embodiments of the invention provide the portable seat apparatus having a support assembly including a support column coupled at one end to the support seat and rotatably coupled at an opposite end to a base which may be coupled to a ground surface. Advantageously, the support seat is distinguishable from a traditional “chair” because the support seat primarily provides back support and may partially support the user's buttocks, thereby allowing the user to bend down during use of the portable seat apparatus.

Referring now to FIG. 1, one embodiment of the present invention is shown in a perspective front view. FIG. 1 shows several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a portable seat apparatus 100, as shown in FIG. 1, includes a support seat 102 having a support seat body 104, i.e., back support body, sized to support a user's back, for example, by disposing an inner surface 106 of the support seat body 104 against a user's mid to low back. In one embodiment, the inner surface 106 is configured to be disposed substantially parallel to the user's back. The term “substantially parallel” is defined herein as extending in a similar or same direction, while allowing nominal deviation in one direction. Said another way, the support seat body 104 may be molded or shaped to contour a user's back. FIG. 1 depicts the support seat body 104 including a first end 108 and a second end 110 opposite the first end 108, and a length 112 separating the first and second ends 108, 110. In one embodiment, the length 112 is approximately 7-11 in inches. In other embodiments, the length 112 may be outside of this range.

In one embodiment, the second end 110 includes a terminal edge 114 configured to be disposed a distance above the user's hamstrings so that the support seat body 104 supports the user's back yet provides the user with the ability to walk, squat, and/or bend over while coupled to the support seat body 104. In one embodiment, the distance between the terminal edge 114 and the user's hamstrings is approximately 1-4 inches. In other embodiments, the distance may be outside of this range. The term “terminal edge” is defined herein as an absolute end of the support seat body 104. In contrast to a traditional “seat” which requires the user to place the entirety of the user's buttocks on the seat, the portable seat apparatus 100 provides the user with the ability to bend down and stabilize the user's back and at least a portion of the user's buttocks on the portable seat apparatus 100, while having free range of motion with respect to the user's legs. In this manner, the user may perform various tasks that require squatting and/or bending over, e.g., gardening, construction installation, plumbing, etc. In one embodiment, the support seat body 104 may include a width 116 of the support seat body 104. In one embodiment, the width 116 is approximately 8-11 in inches. In other embodiments, the width 116 may be outside of this range.

In one embodiment, the second end 110 includes a buttock support member 118 coupled thereto. The buttock support member 118 may be removably or fixedly coupled to the terminal edge 114. In contrast to traditional chairs which include a back support member forming a right angle with respect to the seat, the buttock support member 118 is depicted extending away from the second end of the support seat body 104 in substantially a same direction as the support seat body 104 from the first end 108 to the second end 110 of the support seat body 104.

In one embodiment, the buttock support member 118 may include a curved body 122 having a length 124 of approximately 1.5-3 inches. In other embodiments, the length 124 may be outside of this range. The curved body 122 is conducive for supporting a portion of the user's buttocks when sitting on the buttock support member 118. Said another way, the buttock support member 118 may include a curved configuration suitable for contouring a portion of the user's buttocks to provide back and glute support. In a preferred embodiment, the buttock support member 118 may be sized to receive less than 75% of a user's buttocks. In other embodiments, the buttock support member 118 may be sized to receive greater than 75% of a user's buttocks. As such, when bending down or squatting, the user is provided with the ability to sit on and against the inner surface 106 of the support body 104 and the buttock support member 118, respectively.

The support seat body 104 is configured to remain in a stationary position when subjected to the weight of the user as a result of the support seat body 104 being coupled to a support assembly, as will be explained in further detail herein. In one embodiment, the portable seat apparatus 100 may be configured to sustain up to approximately 325-350 pounds. In other embodiments, the portable seat apparatus 100 may be configured to sustain a weight that is outside of this range.

In one embodiment, in order to couple the support seat body 104 against the user's back, the support seat body 104 may include at least one strap 120 coupled thereto and extending away from the inner surface 106 of the support seat body 104. More specifically, in a preferred embodiment, the portable seat apparatus 100 may include more than one strap 120 a-n used to couple the support seat body 104 to the user in a manner similar to a harness. The indicator “a-n” is intended to represent any number of straps 120 a-n, where the number of straps 120 between “a” through “n” can be any number. The support seat 102 can be said to be portable, i.e., can move with the user. The term “portable” is defined herein in its broadest possible sense as easily carried or moved. The straps 120 a-n may be made of nylon, leather, neoprene, or another suitable material configured to secure the support seat body 104 against the user's back.

In one exemplary embodiment, in use, the straps 120 a, 120 b may be secured through a fastener, e.g., a buckle, (not shown) around a user's first body part. The user's first body part may be the user's chest, waist, or the like. In the same vein, the straps 120 c, 120 n may surround a user's second body part that is different than the first body part. For example, the straps 120 c, 120 n may surround the user's legs and span from the user's crotch region in a direction toward the user's chest area and thereafter couple to the strap 120 b. FIG. 1 depicts only a portion of the straps 120 a-n, however FIG. 1 is not intended to be limiting. Rather, the straps 120 a-n may be any length and may couple to the user through a variety of configurations.

With reference now to FIG. 2, depicting a perspective rear view of the support seat body 104, the support seat body 104 can be seen defining at least one aperture 200 spanning a thickness of the support seat body 104 and sized to receive the strap 120 therethrough. In one embodiment, the support seat body 104 may define a number of apertures 200 a-n sized to receive the straps 120 a-n therethrough.

In one non-limiting embodiment, the support seat body 104 may define a top pair of apertures 200 a, 200 b for receiving the strap 120 a and a bottom pair of apertures 200 c, 200 n disposed a distance below the top pair of apertures 200 a, 200 b for receiving the strap 120 b therethrough. The distance between the apertures 200 a, 200 b and the apertures 200 c, 200 n may vary according to the overall size of the support seat body 104. In other embodiments, the straps 120 a-n may be secured to the support seat body 104 using a hook and loop fastener, an adhesive, or another suitable coupling mechanism. As such, the support seat body 104 may or may not be devoid of the apertures 200 a-n.

With reference now to FIG. 3, in order to provide comfort to the user when coupled to the support seat 102, in one embodiment, the support seat body 104 may include a padding 300 coupled to a support seat shell 302. The padding 300 may be, without limitation, a Ethylene-vinyl acetate (EVA) foam cushion, a fabric stuffed with fiber, an elastomeric material, e.g., silicone rubber or neoprene, etc. The support seat shell 302 may be made of, without limitation, a rigid plastic, rubber, or another suitable material configured to provide support to the user's back. In one embodiment, the padding 300 may be removably coupled to the support seat shell 302 by clipping onto the support seat shell 302. In other embodiments, the padding 300 may be coupled to the support seat shell 302 by a hook and loop fastener, adhesive, or the like. In other embodiments, the padding 300 may be fixedly coupled to the support seat shell 302.

In one embodiment, in order to be disposed against the user's back, the support seat body 104 may include a generally rectangular shape having a right side 304 and a left side 306 opposite the right side 304. As best shown in FIG. 4, depicting an elevational downward-looking view of the support seat body 104, the right and left sides 304, 306 are shown curved inwardly toward each other to at least partially define the inner surface 106 of the support seat body 104. As such, the support seat body 104 is configured to span across a width of the user's back to embrace the user. In other embodiments, the support seat body 104 may be round, square, triangular or another suitable shape. In one embodiment, a top terminal edge of the support seat body 104 may be configured to terminate at an average user's mid to low back. In other words, the support seat body 104 does not extend upwards with respect to the user's mid to low back to support the user's back, as with traditional chairs.

With reference again to FIG. 3, in one embodiment, in order to adjust an angle and/or a height of the portable seat apparatus 100 to fit a user's preference and comfort level, the portable seat apparatus 100 may include a support assembly 308. In one embodiment, the support assembly includes a pivot member 310, a support column 312 couplable to the pivot member 310, a handle 314, a lever 316 and a base 318, as will be explain in further detail below. In other embodiments, the portable seat apparatus 100 may be devoid of one or more of these components and may or may not include additional components as well.

With reference now to FIG. 5 depicting a perspective rear view of the portable seat apparatus 100, the pivot member 310 is shown coupled to an outer surface 500 of the support seat body 104, the outer surface 500 opposite the inner surface 106 (FIG. 1). In this embodiment, the pivot member 310 is depicted coupled to a proximal end 502 of the support column 312. The pivot member 310 may be coupled to the support column 312 using a pin, screw, male and female fastener, or another coupling mechanism, as commonly understood by one of ordinary skill in the art.

Advantageously, the pivot member 310 is configured to provide the user with a support seat 102 that pivots with respect to the support column 312. As such, the support seat 102 may move in conjunction with the user when strapped around the user, such as, when the user bends over and stands up. In one exemplary embodiment, the support seat body 104 may pivot at an angle that is approximately 180° with respect to the support column 312. In other embodiments, the support seat body 104 may pivot at one or more angles greater than or less than approximately 180°. The pivot member 310 may be a pivoting fork, hinge, joint, or other suitable component configured to provide a pivot motion of the support seat body 104 with respect to the support column 312.

With reference now to FIG. 6, depicting an elevational rear view of the portable seat apparatus 100, in one embodiment, in order to adjust a height 600 of the support column 312, the handle 314 is depicted coupled to the lever 316. For example, with brief reference to FIGS. 1 and 2 in comparison to FIG. 6, the height 600 of the support column 312 may be selectively adjusted by the user. In one embodiment, the height 600 of the support column 312 may be adjusted from between approximately 10-12 inches to approximately 36-48 inches. In other embodiments, the height 600 may be outside of this range.

With reference to FIG. 6, in conjunction with FIG. 7 depicting a cross-sectional side elevational view of the portable seat apparatus 100 taken along section A-A of FIG. 6, in one embodiment, the support column 312 may utilize a pneumatic cylinder, i.e., an air cylinder, to easily and conveniently raise and lower the height 600. Pneumatic cylinders, because they are known in the art, will be described generally herein. In use, when the user desires to decrease the height 600, the user may subject the support column 312 to a force, such as the weight of the user, and pull the handle 314 couple to the lever (FIG. 6), causing the pneumatic cylinder to release air. When the user desires to increase the height 600, the user may pull the handle 314 and the support seat body 104 in a vertical direction opposite from a ground surface. The pneumatic cylinder is not intended to be limiting and the height 600 may be adjusted using a non-pneumatic system or another height adjustment mechanism.

With reference to FIG. 7, in one embodiment, the support column 312 may include a distal end 700 opposite the proximal end 502, the distal end 700 being rotatably coupled to the base 318 such that the support seat 102 is rotatable in one or more directions with respect to the base 318, e.g., toward and away from the base 318. Advantageously, in use, such as when the support seat 102 is coupled to the user, the rotational movement between the base 318 and the support column 312 provides the user with the ability to step in forward, backward, and sideways directions. When reaching the user's select destination, the user can lower the support column 312 to sit on and against the support seat 102 for support, thereby reducing the weight placed on the user's knees and back. In order to increase the safety of the portable seat apparatus 100, a locking mechanism (not shown) may be utilized.

With reference to FIGS. 7 and 8, in one embodiment, the support column 312 is rotatably coupled to the base 318 through a fastening assembly 702 so as to permit rotation of the support column 312 about a roll, pitch, and yaw axis. In a preferred embodiment, the fastening assembly 702 is a round joint, i.e., a ball joint, sized to fit and rotate within an aperture 704 defined by the base 318. In other embodiments, the fastening assembly 702 may be another type of joint, a hinge, or another suitable coupling mechanism that provides rotational movement between the support column 312 and the base 318.

In one embodiment, the base 318 is a support structure, e.g., a pedestal, configured to receive and support the support column 312. The base 318 may be made of rubber, rigid plastic, plastic, or another suitable material configured to sustain the weight of the user when leaning against the support column 312 and the support seat 102. In a preferred embodiment, the base 318 is couplable to a ground surface. The term “surface” is defined herein in its broadest possible sense and is generally defined as the outermost or uppermost layer of an object or area. Advantageously, as a user moves when coupled to the support seat 102, the base 318 is configured to remain coupled to the ground surface in a stationary position. The base 318, however, may be selectively moved by a user across the ground surface or may be picked up by the user when a user moves in a direction that exceeds the height 600 of the support column 312. In other embodiments, the base 318 may be coupled to another surface or area.

With reference to FIG. 9, depicting a bottom plan view of the base 318, in one embodiment, the base 318 may include one or more base sections 900 configured to support the weight of the user when the user moves in the forward, backward, and/or sideways directions. In order to increase the safety of the portable seat apparatus 100, in one embodiment, the base 318 may include an anti-slip material or coating coupled thereto, which can be any friction-inducing material. The anti-slip material may be made of rubber, anti-slip tape, or another anti-slip material with a general coefficient of friction greater than the coefficient of friction of the base 318.

Referring now to FIG. 10, in conjunction with FIGS. 1-9, there is provided an exemplary process-flow diagram depicting a method of using a portable seat apparatus, such as the portable seat apparatus 100. Although FIG. 10 shows a specific order of executing the process steps, the order of executing the steps may be changed relative to the order shown in certain embodiments. Also, two or more blocks shown in succession may be executed concurrently or with partial concurrence in some embodiments. Certain steps may also be omitted in FIG. 10 for the sake of brevity. In some embodiments, some or all of the process steps included in FIG. 10 can be combined into a single process.

In said process, the method begins at step 1000 and immediately proceeds to the step 1002 of providing, e.g., bringing into physical existence, a portable seat apparatus, such as the portable seat apparatus 100 of FIG. 1. The present method however, is not limited to use with the portable seat apparatus 100 but may also be used with other seat apparatuses as well.

In one embodiment, the portable seat apparatus 100 preferably, but not necessarily includes, the support seat 102, the strap 120, and the support assembly 308 described in detail above. In step 1004, in one embodiment, the strap 120 be coupled to the user such that the support seat 102 is substantially parallel to the user's back. More specifically, in one embodiment, the strap 120 a may be coupled around the user's chest. In the same vein, the strap 120 b may be coupled around a second one of the user's body parts different than the user's chest, i.e., the user's waist. The straps 120 c, 120 n may be coupled around the user's legs such that the straps 120 a-n together are coupled to the user in a manner similar to a harness. Such examples are provided for illustrative purposes only and are not intended to be limiting.

In a preferred embodiment, the terminal edge 114 of the support seat body 104 is disposed a distance above the user's hamstrings. The distance may be 1-4 inches above the user's hamstrings or alternatively, may be any user selected distance that is comfortable for the user, while allowing the user to walk, bend, squat, and the like. As such, the user is advantageously provided with back support and relatively free range of motion with respect to the user's legs.

In one embodiment, the user may selectively lower the height 600 of the support column 312 using the handle 314 and the lever 316 as described in further detail above. Thereafter, the user may lean against the support seat 102 and the support column 312 with a portion of the user's buttocks sitting on the buttock support member 118 to perform manual labor that requires the user to bend down, squat, etc. Naturally, the user may increase and/or decrease the height to suit the user's preference and/or in accordance with the work the user is performing.

In step 1006, in one embodiment, the method may include moving from a first position to a second position different than the first position. The examples provided herein with respect to the first and second positions are provided for exemplary purposes only and are not intended to be limiting. In one embodiment, the first position may include the support seat 102 disposed substantially parallel to the base 318 (FIG. 5). As such, the first position may provide the user with the ability to secure the straps 120 a-n around the user when standing in an upright manner. In other embodiments, the first position may include the support seat 102 disposed in a non-parallel relationship with respect to the base 318.

In one embodiment, the second position may include the support column 312 disposed at an angle with respect to the base 318 (FIG. 8). In one embodiment, in use, the angle of the support column 312 relative to the base 318 may be between approximately 100° to 45° when the base 318 is coupled to the ground surface. In other embodiments, the angle may be outside of this range. Naturally, the angle of the second position may vary depending on the user's body positioning relative to the base 318. For example, when the user is coupled to the support seat 102 and the user walks 1-2 feet from the base 318 and sit on the buttock support member 118 while leaning against the support seat body 104, the second position may include the support column 312 disposed at an angle that is approximately 50° to 70° relative to the base 318. Such position may be suitable for providing support to the user's back when the user is engaging in tasks that require the user to bend down, e.g., plumbing, construction installation, gardening, and the like. In one embodiment, the second position includes the support column 312 disposed a distance that is less than approximately three feet from a ground surface. In other embodiments, the distance above the grounds surface may be more or less than three feet.
